The invention discloses an aerosol generating device and system for a real ship airflow field test. The aerosol generating device for the real ship airflow field test comprises a rectifying pipeline, a pumping device and a generating unit, the pumping device and the generating unit are installed on the rectifying pipeline, a booster pump and a flow guide pipe are arranged in the generating unit, and incoming flow of the rectifying pipeline is pressurized by the booster pump and then sent to the flow guide pipe. An atomizing sheet is arranged at an outlet of the flow guide pipe so that outlet jet flow can be generated into vaporific aerosol particles and the vaporific aerosol particles can be sprayed into air. According to the aerosol generating device, through an active aerosol generating method, the problem that in the prior art, the concentration of hollow aerosol is too low, and the hollow aerosol cannot be captured and reflected by laser beams, so that outboard wind measurement of a laser radar is affected is solved.

The invention provides montmorillonite solid superacid for flame retardance and a preparation method thereof.According to the montmorillonite solid superacid, a montmorillonite framework and an interlayer are used as cages for packaging and anchoring a superacid ligand, the superacid ligand is a metal atom M, an M-O-Si bond is formed between the metal atom M and the montmorillonite framework or the interlayer, and the M-O-Si bond is formed between the metal atom M and the montmorillonite framework or the interlayer. And the metal atom M is also coordinated and combined with SO4 < 2-> through an S-O-M bond to form a B acid center. The montmorillonite solid superacid prepared by the invention realizes uniform spatial distribution and atomic-scale dispersion, can be used for flame-retardant synergy, improves the flame-retardant efficiency, and solves the problems of low efficiency of a phosphorus-based flame retardant APP and a large amount of smoke during flame-retardant UPR combustion.

This invention belongs to the field of environmental protection equipment technology, specifically relating to a rotary zoned jet cleaning and filtration dust removal device. It includes a cylindrical body, a driving device at the top of the cylinder, a sealing jet cleaning device below the driving device, a sealing zone plate below the sealing jet cleaning device, a filter device below the sealing zone plate, a scraper device below the filter device, and a screw feeder below the scraper device, all mounted on a base. This invention adopts a cylindrical single-unit structure, which can be stacked in multiple layers or arranged in parallel, resulting in a small footprint. The integrated sealing jet cleaning device enables zoned offline cleaning, simplifying the structure. The shared drive scraper device reduces air leakage, and the absence of a ash storage hopper reduces equipment height, leading to low investment costs.
